Dismiss Ionic 4 popover from its component

Question

I have a standard Ionic 4 page (Home) that creates a popover that uses a component (BusinessDetails) with a button that redirects to a new page (RequestTurn). However, when I click on that button, the popover is not dismissed and is renders on top of my RequestTurn page. I guess I need to manually dismiss it from the component (BusinessDetails), but I don't know how to access the instance of the popover from there, because it was created in the Home page. Is there a way to do this?

home.page.ts

presentModal(business:Business, event: Event) {
this.popoverController.create(({
    component: BusinessDetailsComponent,
    cssClass: "business-popover",
    showBackdrop: true,
    componentProps: {
        business: business
    }
}) as any).then(popover => popover.present()); }

business-detail.component.ts

goToRequestTurn(id: string) {
   //Need to dismiss popver here (?)
   this.router.navigateByUrl(`/request-turn/${id}`); }

Thanks for your help.

Solution 1

add private popoverController: PopoverController to the component constructor

then write a function like this and call it when you want to dismiss the modal

 async DismissClick() {
await this.popoverController.dismiss();
  }

Solution 2

I solved this problem as follows: In parent component I have passed callback as prop to child component:

const popover = await this.popoverController.create({
  component: PopoverComponent,
  event: ev,
  componentProps: {
    onClick: () => {
      popover.dismiss();
    },
  },
});
await popover.present();

And in PopoverComponent I have added @Input() onClick; which called when the user clicks:

...
@Input()
public onClick = () => {}
...
afterClick() {
  this.onClick();
}

Do you mean "to the component constructor"? Because that's where I need to dismiss it from, but it looks to me like doing that will inject a new instance of the controller, so would not be dismissing the original one. I'll give it a try, anyway. Thanks.

yes the component constructor,sorry my mistake.let me know if you succeeded. good luck

It did work, thanks for the help. So, that means that the PopoverController you inject is actually a sinlgeton, correct? Otherwise, why would it close the instance injected to the constructor of the Home page?

Wrong. you are taking input as 'onClick' and on 'afterClick' writing 'this.click()'

Thank you, it helped me . Very strange, but the first time it did not work. When I tried this method after a while, it started working O_o
